Description

Technical Field

[0001] The utility model belongs to the field of water and fertilizer irrigation, and particularly relates to water and fertilizer irrigation equipment. Background Art

[0002] Existing commonly used water and fertilizer irrigation equipment such as Figure 11 As shown, its working principle is as follows: first, water is pumped into the head filter 101 for filtration to remove impurities such as mud, suspended matter, etc. in the water. Part of the purified clean water continues to flow along the main pipe 102, and the other part enters the pressure differential fertilization tank 104 connected in parallel to the main pipe 102 through the water inlet pipe 103; the clean water entering the pressure differential fertilization tank 104 will dissolve the fertilizer pre-placed in the tank to form a solution. Since the water inlet pipe 103 is connected to the upstream high-pressure area of ​​the main pipe 102 and the fertilizer outlet pipe 105 is connected to the downstream low-pressure area, under the action of the pressure difference, the fertilizer solution is pressed out of the pressure differential fertilization tank 104 and flows back to the downstream of the main pipe 102, and mixes with the mainstream clean water in the main pipe 102 to form a water-fertilizer mixture; the water-fertilizer mixture is filtered again by the secondary filter 106 to remove possible fertilizer residues. Finally, the water-fertilizer mixture flows out of the water outlet and is transported to the roots of the crops.

[0003] However, the water and fertilizer irrigation equipment in the prior art has the following defects: 1. The water and fertilizer irrigation equipment in the prior art only relies on the pressure impact of water when it enters the pressure differential fertilization tank 104 from the water inlet pipe 103 to achieve dissolution of the fertilizer, which has obvious limitations: the impact force of the water flow is concentrated locally, and it is difficult to act on the fertilizer in the corners of the bottom of the tank or in the thicker accumulated areas. In addition, the fertilizer particles are uneven in size and solubility, which further makes the water flow and fertilizer insufficient in contact and incomplete mixing, and ultimately causes insufficient and uneven dissolution of the fertilizer. Although the secondary filter 106 can filter larger fertilizer residues, it cannot overcome the problem of insufficient and uneven dissolution of the fertilizer. The insufficiently dissolved fertilizer particles are prone to local accumulation in the field, resulting in an imbalance in nutrient concentration around the crop roots, which may cause local fertilizer damage and affect the normal metabolism of the plants; the uneven distribution of fertilizer in the water will cause obvious differences in crop growth and poor group growth. Inconsistency, reducing yield and quality; 2. In the prior art, the operation process of adding fertilizer to the pressure differential fertilization tank 104 is quite cumbersome: it is necessary to first close the valves of the water inlet pipe 103 and the fertilizer outlet pipe 105 to cut off the connection with the main pipe 102, and then open the feeding port 107 to complete the fertilizer addition, and then ensure that the feeding port 107 is tightly sealed, and finally slowly restart the valve to restore the system operation. This series of steps not only prolongs the operation time, but also places extremely high requirements on the sealing of the feeding port 107. A loose seal of the feeding port 107 may cause pressure imbalance in the tank, affecting the fertilization efficiency, which not only brings many inconveniences to the actual operation, but also limits the stability and convenience of the fertilization process; 3. In the prior art, it is impossible to observe the water and fertilizer conditions in the pressure differential fertilization tank 104, so it is impossible to adjust the appropriate amount of water to adapt according to the amount of fertilizer added, and the ideal water and fertilizer concentration cannot be guaranteed.

The water filtered by the filter 2 is pressurized by the booster pipe 4 and enters the detachable fertilizer-dissolving component 3. The water-fertilizer formed by fully dissolving the fertilizer in the detachable fertilizer-dissolving component 3 enters the tank body 11. The water-fertilizer in the tank body 11 flows into the centrifugal water pump 7 through the outlet pipe 14 and the flange elbow 6. The centrifugal water pump 7 transports the water-fertilizer to the irrigation area to complete the irrigation work; the connecting pipe 5 on the front side of the tank body 11 is connected to the inside of the tank body 11 to form a communicating vessel principle, which can intuitively display the amount of water and fertilizer in the tank.

Above the horizontal plane of the diverter nozzle 33 in the dissolving chamber 31, a first filter screen 34 and a second filter screen 35 are provided in sequence from bottom to top; in this arrangement, the dissolving chamber 31 of the cylindrical structure provides a relatively closed structure for the mixed dissolution of fertilizer and water. The space is large, and the punching water inlet pipe 32 above it can introduce high-pressure water flow, using the impact force to preliminarily crush and stir the fertilizer; the first filter 34 and the second filter 35 arranged from bottom to top above the horizontal plane of the diverter nozzle 33 in the dissolution chamber 31 can intercept and disperse the incompletely dissolved fertilizer particles in a graded manner, and at the same time cut the water flow to enhance the flushing and dissolution effect, thereby improving the efficiency and quality of water-fertilizer mixing; finally, the diverter nozzle 33 in the circumferential array at the lower part of the dissolution chamber 31 can divert the water-fertilizer mixture into multiple water streams, and promote the uniform mixing of water and fertilizer in the tank through multi-directional impact.

[0033] The detachable fertilizer dissolving component 3 also includes a fertilizer channel 36, the lower end of the fertilizer channel 36 is connected to the side wall of the punching water inlet pipe 32; wherein, the section of the fertilizer channel 36 close to the punching water inlet pipe 32 is inclined, and the section away from the connection between the fertilizer channel 36 and the punching water inlet pipe 32 has an upper end surface of the tube body of the section being a horizontal plane, and a first snap-fit ​​cover 37 is provided on the horizontal plane, as shown in FIG. Figure 5 and Figure 6 As shown, Figure 5 The first buckle cover 37 is in the open state, Figure 6 The first snap-fit ​​cover 37 is in a closed state when the present invention is not in use, so as to prevent external impurities from contaminating the interior of the detachable fertilizer dissolving component 3. When adding fertilizer, the first snap-fit ​​cover 37 is opened and the lower end of the funnel is aligned with the upper end of the fertilizer channel 36. After the fertilizer is introduced into the fertilizer channel 36 through the funnel, it enters the stamping water inlet pipe 32 and finally flows into the dissolving chamber 31. The fertilizer channel 36 provides an independent path for adding fertilizer, and its lower end is connected to the stamping water inlet pipe 32, so that the fertilizer can directly enter the water flow channel for mixing; the section close to the stamping water inlet pipe 32 is inclined, which can use gravity to guide the fertilizer to slide smoothly into the stamping water inlet pipe 32, avoiding fertilizer accumulation and blockage; the upper end surface of the section away from the connection is a horizontal plane and is provided with a first snap-fit ​​cover 37, which is convenient for stably placing the funnel to facilitate adding fertilizer, and the first snap-fit ​​cover 37 can be closed when the present invention is not in use to prevent impurities from entering and polluting the interior of the equipment.

[0034] The circumferential outer edge of the upper end surface of the dissolution chamber 31 extends outward to form a first flange 38, and the upper end surface of the mounting seat 13 is provided with a bolt hole corresponding to the first flange 38. The lower end surface of the first flange 38 is in contact with the upper end surface of the mounting seat 13, and the bolts pass through the first flange 38 and the bolt holes of the upper end surface of the mounting seat 13 from top to bottom to achieve a fixed connection between the mounting seat 13 and the detachable fertilizer dissolving component 3; in this arrangement, the detachable connection structure of the flange and the bolts facilitates the disassembly and assembly of the fertilizer dissolving component, provides convenience for subsequent cleaning, maintenance or component replacement, and takes into account the stability of equipment operation and the convenience of maintenance.

[0035] The boost pipe 4 is a pipe body whose inner diameter gradually decreases from the upper end to the lower end along the axial direction; the circumferential outer edge of the upper end of the boost pipe 4 extends outward to form a second flange 41, and the circumferential outer edge of the lower end of the boost pipe 4 extends outward to form a third flange 42, wherein the second flange 41 and the fourth flange 21 formed by extending outward from the outer edge of the water outlet of the filter 2 are connected by bolts, so that the boost pipe 4 is connected to the water outlet of the filter 2; in this setting, the inner diameter of the boost pipe 4 gradually decreases from the upper end to the lower end along the axial direction. According to the principles of fluid mechanics, the pressure of water can be increased due to the reduction of cross-sectional area when flowing in the pipe, thereby forming a high-pressure water flow at the lower end, thereby enhancing the impact effect on the fertilizer in the dissolution chamber 31 and helping the initial dissolution of the fertilizer.

[0036] The circumferential outer edge of the upper end face of the punched water inlet pipe 32 extends outward to form a fifth flange 39. The upper end face of the fifth flange 39 fits with the lower end face of the third flange 42 and the two are connected by bolts, thereby realizing the connection between the detachable fertilizer dissolving component 3 and the boosting pipe 4.

A shock-absorbing supporting assembly 8 is provided above the connecting plate 121 and between the left and right supporting limit plates 122. In this arrangement, the horizontal connecting plate 121 above the support frame 12 provides a stable installation base for the supporting limit plates 122 and the shock-absorbing supporting assembly 8 and is beneficial to the structural stability of the support frame 12. The vertical supporting limit plates 122 on the left and right sides above the connecting plate 121 can form a lateral limit for the shock-absorbing supporting assembly 8 to prevent it from deviating in the horizontal direction during the operation of the equipment. The shock absorbing supporting assembly 8 located on the connecting plate 121 and between the support limit plates 122 can support the centrifugal water pump 7 installed thereon, and at the same time buffer the vibration generated when the water pump is working through its own shock absorbing function. The cooperation of the three not only provides a stable installation space for the centrifugal water pump 7, but also ensures the working stability of the shock absorbing assembly through the limitation, thereby improving the overall operation reliability of the equipment. During installation, there are bolt holes on both sides of the length direction of the shock absorbing supporting assembly 8 that pass through its height direction, and the bolts pass through the bolt holes to fix the shock absorbing supporting assembly 8 on the connecting plate 121.

[0040] The rear side of the communicating pipe 5 is provided with a stabilizing part 9, which comprises an arc-shaped bracket 91 and a connecting base 92, wherein the connecting base 92 is welded to the front side of the tank body 11 of the fertilizer tank 1, and the inner arc surface of the arc-shaped bracket 91 is attached to the circumferential side wall of the communicating pipe 5; in this arrangement, the stabilizing part 9 provides additional support for the communicating pipe 5 through the cooperation of the arc-shaped bracket 91 and the connecting base 92, the connecting base 92 is welded to the front side of the tank body 11 to form a stable fulcrum, and the arc surface of the arc-shaped bracket 91 is attached to the side wall of the communicating pipe 5 to prevent the communicating pipe 5 from tilting or being broken under pressure, thereby ensuring the stable relative position of the communicating pipe 5 with respect to the tank body 11 and being conducive to the stability of the utility model.

[0041] Specific working principle:

[0042] The operator first adds fertilizer through the fertilizer channel 36 of the detachable fertilizer dissolving component 3. Specifically, the operator opens the first snap-on cover 37 at the upper end of the fertilizer channel 36 and guides the fertilizer into the inclined channel section through the funnel. The fertilizer slides into the punching water pipe 32 with the help of gravity and finally enters the dissolution chamber 31. The water source is filtered by the filter 2 and enters the boosting pipe 4 from the water outlet of the filter 2. Since the inner diameter of the boosting pipe 4 gradually decreases from the upper end to the lower end along the axial direction, according to the principle of fluid mechanics, the pressure of the water increases as the cross-sectional area decreases when the water flows in the pipe. The high-pressure water flow is injected into the dissolution chamber 31 through the punching water inlet pipe 32. The high-pressure water flow forms an impact effect in the dissolution chamber 31, initially breaking and stirring the fertilizer; the fertilizer particles that are not completely dissolved will be intercepted in order by the second filter 35 and the first filter 34 provided in the dissolution chamber 31. The water flow is cut and dispersed when passing through the filter, further enhancing the flushing and dissolving effect of the fertilizer. The dissolved water-fertilizer mixture passes through the diversion nozzle 33 of the circumferential array at the lower part of the dissolution chamber 31, and is diverted into multiple streams of water and sprayed from different directions to impact the tank body. The existing solution inside 11 or in the tank body 11 promotes uniform mixing of water and fertilizer; the lower part of the connecting pipe 5 is connected to the inside of the tank body 11 to form a communicating vessel principle. The body of the connecting pipe 5 is matched with the scale line 52 on the front side. The operator can read the liquid level data intuitively, so that the water intake can be accurately adjusted in combination with the amount of fertilizer added to ensure the ideal water and fertilizer concentration. When the water and fertilizer in the tank body 11 reaches the preset amount, the water and fertilizer flow out through the outlet pipe 14 at the bottom of the tank body 11, and are connected to the water inlet of the centrifugal water pump 7 through the flange elbow 6 to enter the centrifugal water pump. Inside pump 7, centrifugal water pump 7 transports water and fertilizer from tank 11 to the irrigation area. The vibrations generated by the operation of centrifugal water pump 7 are transmitted through the bottom to shock-absorbing support assembly 8, thereby reducing vibration and ensuring stable operation of the equipment. During operation, the operator can observe the amount of water and fertilizer in tank 11 in real time via the scale line 52 on the connecting pipe 5. When the liquid level falls below the preset value, the operator can open the first snap-fit ​​cover 37 again to add fertilizer, and repeat the above mixing process through the high-pressure water flow of the booster pipe 4, achieving uninterrupted fertilization. When the equipment stops operating, the second snap-fit ​​cover 51 at the upper end of the connecting pipe 5 and the first snap-fit ​​cover 37 on the fertilizer channel 36 are closed to prevent external impurities from entering the tank 11 and dissolution chamber 31, ensuring the internal cleanliness of the equipment.
